The Lucu package

Lucu is an HTTP daemonic library. It can be embedded in any
Haskell program and runs in an independent thread.
Lucu is not a replacement for Apache. It is intended to be
used to create an efficient web-based application without
messing around FastCGI. It is also intended to be run behind a
reverse-proxy so it doesn't have some facilities like logging,
client filtering and so on.
